I have connected a spare pair of speakers the SURR BACK/ZONE 2 speaker terminals and made the necessary setup menu changes. All of the inputs (CD, DVD, FM, etc.) work fine with the zone 2 setting except the Video 3 input which is connected to my Direct TV HD receiver. When it is selected, I hear nothing. I listen to a lot of the digital music channels and want to pipe them out to my deck where the zone 2 speakers are located. Any advice before I tear my home theater apart and take the receiver in for service? Thanks in advance for your assistance.
